I have a 12x42 SWFA mounted on my 250AI tube gun, going out west this summer to camp, shoot and fish with the wife. Setting up the tube gun for rockchucks, and developed a load using Sierra 90gr, tipped blitz bullets at 3200fps. Rifle is zeroed at 200. I have the dials set and shot to 700. Looking at the dials a few days ago, I discovered that the riticule and dials matched within .2 mils out to 600 yrds. So I set the dial at 400. Now I could hold both over and under using the milquad. I shot to conferm this yesterday. Altho I`ve used both mil dots and the quad for quick reference, I`ve never had a load that matched this closly befor at ranges to 600 with minamal adjustment on my part. Very easy...on larger targets like deer, and with a proper bullet, it would be great.
Anyone else doing this???with what, and what load?
Thanks
